The term periodical cicada is commonly used to refer to any of the seven species of the genus Magicicada of eastern North America, the 13- and 17-year cicadas.They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year.
Brood XIX includes all four different species of 13-year cicadas: Magicicada tredecim (Walsh and Riley, 1868), Magicicada tredecassini (Alexander and Moore, 1962), Magicicada tredecula (Alexander and Moore, 1962), and the recently discovered Magicicada neotredecim (Marshall and Cooley, 2000). 2011 was the first appearance of Brood XIX since the discovery of the new species, which was first ...
Brood XIII of the 17-year cicada, which reputably has the largest emergence of cicadas by size known anywhere, and Brood XIX of the 13-year cicada, arguably the largest (by geographic extent) of all periodical cicada broods, were expected to emerge together in 2024 for the first time since 1803.
Of the species emerging in 2024, Brood XIII is a 17-year periodical cicada, and Brood XIX is a 13-year species. When will the cicadas emerge?

Some species have much longer life cycles, such as the North American genus, Magicicada, which has a number of distinct "broods" that go through either a 17-year (Brood XIII), or in some parts of the region, a 13-year (Brood XIX) life cycle [51] The long life cycles may have developed as a response to predators, such as the cicada killer wasp ...
